Noisy channels reconstruction.

<p>Graph A shows 100 samples of the 32 electrodes time signals from the first session of User 1. Solid lines represent the artifact-free electrodes (±50 uV, common range of EEG signals), dotted and dashed lines represent the noisy channels (PO7, C5 and CPZ, out of ±50 uV range). Each noisy channel is replaced by the average value of the surrounding channels. Graph B shows the reconstructed signal.
